Microbialorganism

Salmonella is one of the most common microbial organisms thatfalls under kingdom Animalia. As a microbial organism, it istoo tiny to be seen with the naked eye and can only be seen using amicroscope. The name Salmonella is actually a genus name for agroup of rod-shaped bacteria under the Proteobacteria phylum.Nonetheless, the name is commonly used to refer to several species ofbacteria that cause diseases such typhoid and food poisoning. Theyare primarily found in the intestinal tracts of most domestic animalssuch as cattle, chicken, and dogs.

Plants

1. Moss- falls underbryophyte group. This is a commonly occurring plant found in wet ordry surfaces such as rocks and barks of trees.

2. Corn-falls underangiosperm group (flowering plants). This is a common plant grown inlarge plantations in America for human and animal consumption.

Animals

Dog-vertebrate

Earthworm -invertebrate

Dog- Canislupus familiaris

Figure1 A domestic dog (German shepherd)

I own a pet dog, which is purebred German shepherd. The dog fallsunder the kingdom Animalia. The taxonomic classification of dogs hadundergone numerous changes with intention of declassifying domesticdogs from the same species as wolves. Canis is applied to agenus including dogs and wolves. Canis lupus is, however,applied to identify a subspecies of domestic dog. Ideally,classifying wild dogs and domestic dogs differently is an ongoingdebate. However there is no scientific identification of specificbreeds of dogs.

Earthworm orlobworm- Lumbricus terrestris

As for the earthworm, I found it in my neighbor’s garden. There aremany such earthworms in my neighborhood in Fort Collins. Earthworms,as the name suggests, are commonly found in humid soils. They canalso be found in decomposing organic matter, which they feed on. Theytend to be slimy or wet and have segmented bodies.

Domain

Salmonella

The Salmonella belongs to the Proteobacteria phylum andfamily of Enterobacteriaceae and the genus of Salmonellalignieres. All species of Salmonella can infect humans.Two of the most common species of this microbe are Salmonellaenterica and Salmonella bongori.

Corn

Corn is one of the most common plants in America and around theworld. In some countries, it is also called maize. The plant fallsunder the phylum Angiosperm for the simple reason that itproduces flowers. It also falls under the class Liliopsida becauseits seed has one cotyledon. Thus, the scientific name for the plantis Zea mays L.

Moss

Moss falls under the phylum Bryophyte. This phylum comprisesof plants that grow on land (i.e. terrestrial) but also lack majortissues found in other plants commonly used in transporting water andnutrients. Also, plants in this phylum do not produce flowers orseeds and instead rely on spores for fertilization. The plant belongsto the family Bryceae. The scientific name is Bryumcaespiticium Hedw.

Animals

Vertebrae

Animals in this phylum are characterized by an internal skeleton. Theskeleton supports these animals to stand upright, facilitate movementas well as protect major internal organs. The skull, as part of theskeleton, protects the brain while the ribcage protects the heart,liver, and lungs. Some other animals such as insects and earthwormshave external skeletons.

Invertebrae

The earthworm belongs to the phylum Annelida, familyLumbricidae, and genus of Lumbricus. The scientificname is Lumbricus terrestris.

As shown above, thesurrounding environment is evident of the diversity of life. Bothplants and animals with different features continue to interact indiverse ways as players in the natural order of things. Theirfeatures determine how they are taxonomically classified.
